Talvez deva tentar algumas variações de ortografia:
efficient programming » efficient processing (Expandir a busca), fragment programming (Expandir a busca)
are efficient » more efficient (Expandir a busca), are sufficient (Expandir a busca), an efficient (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
coder coder » coder decoder (Expandir a busca), code code (Expandir a busca), decoder codec (Expandir a busca)
coder are » code are (Expandir a busca), code art (Expandir a busca), older are (Expandir a busca)
in python » _ python (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( coder coder are efficient programming ) OR ( in python python python programming ))~.
